First Claim
Patent Images
1. A method for rotating rotationally symmetrical containers along a conveying surface comprising the steps of:
- a. limiting the conveying surface laterally by at least two railings, the distance between the railings in a first area being limited to at least 1.2 to 1.6 times the diameter of the container;
b. transporting the containers under back pressure; and
c. arranging one of two consecutive containers stable against one of the at least two railings and the other stable against the other of the at least two railings in the direction of conveyance after the first area by means of at least one worm arranged adjacent to the conveying surface, thereby rotating the containers.

Abstract
Rotationally symmetrical containers (10) are transported under backup pressure on a conveying surface (12) limited laterally by railings (14). For rotating the containers (10) at a predetermined site along the conveying surface (12), one of two consecutive containers (10) is arranged stable against one railing (14) and the other stable against the other railing (14) in the direction of conveyance after the site at which the containers are to rotate.
